Ramsey and Monreal had doubts about injury due to calf and knee injuries. But it seems that Emery will be able to call both players for the first match of the Premier League of Arsenal tomorrow, after working with the team in a training session in the Emirates Stadium tonight. It means that Ramsey could take his place in the central midfield with Emery who will choose between Granit Xhaka, Lucas Torreira, Mohamed Elneny and the summer signing Matteo Guendouzi. Uncertainty about Monreal meant Ainsley Maitland-Niles was destined to take on the role of left-back but the Spanish expert could now take his place in the team. Speaking to journalists on Friday, Emery said she was working with Maitland-Niles to become familiar with the position. He said: "Today, Nacho Monreal has started training with the team, and Danny Welbeck has arrived this week, but Sunday will be too early to start playing." The other players are doing well and we are working on the possibility of working with Ainsley, who has experience in this [left-back] position. "We want to give him confidence." I'm not sure why I'll decide tomorrow [Saturday] the first 11, but Ainsley is the player who started the last game against Lazio. "Elsewhere, Pierre-Emerick Aubameyang was all smiling while training with his teammates, while Emery looked at home in his new environment while giving instructions to Welbeck and Mesut Ozil. And the Spanish coach says he is optimistic about the new season. "My first message [to the players] it's clear, "he said." Think about every game. Enjoy the challenges of every game. "I'm looking for every day and the players are smiling in training with a great collective spirit, they're working and they're finishing up tired but with a smile on their face." For me, this is the best message I can give to supporters. It's for that [reason that] my message for Sunday is [one of] optimism."
